Re: How accurate are the MSD RPM Chips. PostSat Oct 03, 2009 1:06 pm. Funny you guys mention this..... I bought a 7al3 at the beginning of the year. After I hooked it all up I went throught all the rpm switches and put the test 3000 chip in it and went right to 3000 on all 4-5 rpms ports.
Restart the engine and check if the idle RPM has dropped. If there's no change in the idle speed, the solenoid has a problem. 4. Use an ohm meter to check the solenoid by attaching the positive lead to the VPWR (vehicle power pin) and the negative lead to the IAC pin. 1  Your resistance reading should be between 7.0 ohms and 13.0 ohms.
